Question 754182
evaluate  (2a^2 b^4)^4 b/(6a^2 b)^3

fist step is to multiply the exponent that raises the parenthesis by exponents within the parenthesis

(2^4*a^8*b^16) * b/(6^3*a^6*b^3)

multiply by b

2^4*a^8*b^17 / 6^3*a^6*b^3

reduce by canceling the powers of like terms and compute where possible

16*a^2*b^14 / 216

2*a^2*b^14 / 27
